Abstract (en)
[origin: EP0400370A2] A method for recovering heat from the exhaust gas (7) of a gas turbine (1) operating in a combined cycle power plant where heat is recovered by transferring it to feedwater in a heat recovery steam generator (9). Acid corrosion is avoided by regulating the heat transferred from the exhaust gas (7) to the feedwater heater (25) depending on the sulfur content of the fuel burned in the gas turbine (1).
